These counters collects the information for remote call and copies the information to a buffer shared by user. Collection of DSP performance counters is also added as part of this change. DSP updates the performance information in the metadata which is then copied to a buffer passed by the user.

After message is sent, there is a wait on a completion object at driver which is completed when DSP response is received. There is a possibility that a signal is received while waiting causing the wait function to return -ERESTARTSYS. In this case the context should be saved and it should get restored for the next invocation for the thread. Adding changes to support saving and restoring of interrupted fastrpc contexts.
